Which crypto gives passive income?

As a cryptocurrency enthusiast, I'm curious to know which digital assets offer the potential for passive income. Could you elaborate on some of the cryptocurrencies that provide such opportunities? Are there specific tokens or coins that are known for their dividend-paying mechanisms or staking rewards? Furthermore, are there any key considerations one should take into account when investing in crypto for passive income, such as risks associated with volatility or the long-term sustainability of the underlying projects? Your insights would be greatly appreciated.
